如何打印在我的字符串中找到的字符？

# 假设我们有一个字符串和一个字符
my_string = "Hello, World!"
char_to_find = "W"

# 遍历字符串，找到字符并打印
for i, char in enumerate(my_string):
    if char == char_to_find:
        print(f"Found '{char}' at index {i}")

// 假设我们有一个字符串和一个字符
let myString = "Hello, World!";
let charToFind = "W";

// 遍历字符串，找到字符并打印
for (let i = 0; i < myString.length; i++) {
    if (myString[i] === charToFind) {
        console.log(`Found '${charToFind}' at index ${i}`);
    }
}

public class Main {
    public static void main(String[] args) {
        // 假设我们有一个字符串和一个字符
        String myString = "Hello, World!";
        char charToFind = 'W';

        // 遍历字符串，找到字符并打印
        for (int i = 0; i < myString.length(); i++) {
            if (myString.charAt(i) == charToFind) {
                System.out.println("Found '" + charToFind + "' at index " + i);
            }
        }
    }
}

using System;

class Program {
    static void Main() {
        // 假设我们有一个字符串和一个字符
        string myString = "Hello, World!";
        char charToFind = 'W';

        // 遍历字符串，找到字符并打印
        for (int i = 0; i < myString.Length; i++) {
            if (myString[i] == charToFind) {
                Console.WriteLine($"Found '{charToFind}' at index {i}");
            }
        }
    }
}
